In general deterrent sentencing means someone gets clobbered as a warning - and that is a bit dodgy from a moralistic viewpoint
On the other hand for far too long we've seen people misbehaving on aircraft - they really don't seem to understand that they are in a thin tube with 100-500 others travelling at 850 ft/sec where you can't breathe outside . They behave as if hey are in a bar in San Arenal or some other dump where the biggest risk is tripping over the kerb.
Regretfully this sentence will have far more effect than pages of hand wringing exhortation.......................
